|| nigel found magnitude variation problems due to zeropoint offset|| ipp  || Bill  || yes    ||  
|| stackdetections some have kronflux = 0 and some have kronflux = -999 why?  || dvo? || Heather ||  ||
||  ndetections != ng + nr + ni + nz + ny in many cases   || dvo || heather/gene ||

|| stsci has object count integrity problems - investigate and compare to conrad s                     ||       || heather      ||          ||

|| edge problem part 1: psps and ipptopsps both need bigger ranges for SAS || ipptopsps/psps ||  heather/thomas ||
|| edge problem part 2: integrity will always fail near edges heather thinks || || ken || we decided we will accept that||
|| -999s in ndetections :  see [[wiki:SA9ndetections]]  12k from failed batch, 60k from ipptopsps not having enough ra/dec range, 2k need investigation|| || heather  
|| ken's funny meanpsf vs kronpsf mag problem (sounds similar to previous problem - exposure time again ? || ipptopsps || heather
